Industrial applicibility
Present invention description tooth block 100.Tooth block 100 can each be detachably mounted to the claw of removal tool.Otch can be permitted
Perhaps the power produced during dismantling operation can dissipate around tooth block 100.Otch can allow power to dissipate to avoid stress in tooth block 100
Excessive forces at point.Power through dissipation can reduce in specific stress point, to reduce failure or abolish.Stress point can be adjacent to and tear open
Except instrument.In one embodiment, stress point can be located in removal tool.
During dismantling operation, crushing force can be produced and power is abolished.Crushing force can be by may move claw by just removing
Material is applied in the corresponding impingement members 14 on stationary jaw.Crushing force can be directly related with the pressure in cylinder.Crushing force
Direction can be by may move the corresponding shock part 14 on claw by the sophisticated axis of tooth and maximum claw aperture
Toothed portion 62 is limited.The size of crushing force is the crushing force of removal tool.Crushing force can removal tool claw fully
During opening in its maximum and claw close during be decreased to about the 50% of the maximum.The size of crushing force is in maximum
Measured under cylinder pressure.
Abolishing power can be perpendicular to crushing force.Abolish power by the movement of cylinder can put on tooth block during dismantling operation
100.When crushing force is acted on tip, the big I for abolishing power is calculated as between the material of tooth and tip and impingement members 14
Frictional force.When tip is hooked in object and removal tool is used as rod member to destroy or move the object, it can produce and abolish
Power.
It may be not the main power needed for dismantling operation to abolish power, and may be had not for tooth cover or tooth block on the contrary
Sharp stress.Otch 16 may be such that abolishing power can dissipate.During dismantling operation, otch 16 may be such that tooth block 100 is amenable to deformation
Power is abolished to dissipate.The relatively large part of power can be by antetheca 18, specifically in front contact surface 24 and anterior interior table
Dissipated between face 30.Tooth block 100 can be subjected to elastic deformation.Impingement members 14 can rotate relative to corresponding coupling part 48.
Therefore, the present invention include applicable law allow all modifications of the theme enumerated in appended claims with
Equivalent.In addition, unless otherwise indicated herein, said elements are contained in its any combinations being possible in modification by the present invention
Lid.
In the case of the technical characteristic referred in any claim is followed by reference, reference merely to
Increase these claims intelligibility and including, therefore either have reference or reference missing will not
Technical characteristic as described above or the scope to any claim element have any restriction effect.
It will be appreciated by those skilled in the art that, the present invention can embody in other specific forms, without departing from this hair
Bright or its essential characteristic.Therefore, embodiment before is considered as being illustrative rather than limiting described herein in all respects
The present invention.Therefore the scope of the present invention will be pointed out by appended claim, rather than description above, and therefore in right
It is required that equivalent meaning and scope in all changes be intended to and be included in.
